Self-balancing type inertia braking device

The invention relates to a self-balancing type inertia braking device, and belongs to the technical field of special vehicles. By reasonably designing a traction rod assembly and a driving brake assembly, the self-balancing type inertia braking device is simple in structure, there is no need to provide a hydraulic oil output source by a motor tractor, the impact or collision between a trailer andthe motor tractor can be avoided, and potential safety hazards are eliminated; meanwhile, by installing a traction rod assistant spring for self-balancing the dead weight of the traction rod assembly,manual operation is convenient, and time and labor are saved. 本发明涉及一种自平衡式惯性刹车装置，属于特种车辆技术领域。本发明的一种自平衡式惯性刹车装置，通过对牵引杆总成、行车制动总成的合理设计，使得装置结构简单，且不需要牵引车提供液压油输出源，在急刹或减速时，能够避免拖车与牵引车发生冲击或碰撞，消除安全隐患；同时，通过安装牵引杆助力弹簧自平衡牵引杆总成自重，方便人力操作，省时省力。
